In a World Where Chastity Is Reversed, I Kept Provoking Girls Until Things Went Too Far

Chapter 3: Noisy After School

The moment the after-school chime rang, my desk was once again surrounded by the girls.

This was everyday life in this world—but honestly, I enjoyed it just a little bit.

“Hey, Kouta! Let’s take a purikura today! Absolutely! Look, they have that new frame out!”

Yuri, bursting with energy, leaned over my desk until she was practically face-down on it. Her face was way too close, but her smile was so bright that I couldn’t bring myself to complain.

“Huh? What’s that, so childish. If you’re going to do something like that, Kouta should come over to my place and watch videos. We can lounge around on the bed.”

Aya slung her arm around my shoulder as if it were the most natural thing in the world and pressed her body against mine. The soft sensation set off alarm bells.

“…You two are idiots. Kouta is already set to do homework with me today.”

The cool Otowa extended her notebook toward me matter-of-factly. Her eyes were cold. She wasn’t smiling. When I met her gaze… a chill ran down my spine.

I sighed inwardly.

—In the end, I was the one provoking the girls and enjoying their reactions. I knew this was what caused everything to spiral out of control, but I couldn’t stop.

“Hey… you all…”

Even as I sighed to myself, I couldn’t help but indulge my bad habit.

“You’re all just talk. If you really like me, then show me some proof.”

Silence.

In the next instant, all three pairs of eyes gleamed fiercely.

—Oh no, was that a landmine?

“Proof, huh… Then right here and now, let’s take a two-shot! I’ll set it as my wallpaper forever.”

Yuri whipped out her smartphone and yanked me toward her forcefully.

“Wait a sec! I’ll prove how serious I am about Kouta. Here, lap pillow!”

Aya slapped her thigh with a bang and tried to lay my head on her soft-looking lap.

“…How stupid. Proof is easy. I’ll make you say ‘I like you’ right now. Recording it will be enough.”

Otowa thrust her smartphone toward me with a cold expression, but her ears were beet red.

The whole class started buzzing with “Huh, what’s this?” and “A real confession showdown!?”

One of the onlooker girls climbed onto a desk and shouted, “Can I join in too!?”

I desperately tried to laugh it off.

“H-hey, that was a joke! You don’t have to show any proof for real!”

But the three wouldn’t back down.

“We won’t stop until we show it!”

The classroom instantly turned into a chaotic battlefield of a “proof showdown.”

My desk became a mess of smartphones and absurdly long love letters.

As I tried to bolt from my chair, all three grabbed my arms at once.

And then—.

“You girls! Hold it right there!”

The classroom door flew open with a bang.

My sister Rika made her entrance, standing imposingly.

“Kouta is my little brother! Isn’t it embarrassing to fight over him like this!?”

The atmosphere in the classroom shifted in an instant. But instead of backing down, the three—.

“Whoa, here comes the ‘big sister privilege.'”

Aya sneered.

“Using your brother as a shield to act superior? Isn’t that a bit lame?”

“Yeah! It’s totally unfair to have an advantage just because you’re his sister! Don’t think you can squeeze into Kouta’s ‘girlfriend slot’ because you’re blood-related—that’s a huge mistake!”

Yuri snapped back loudly.

“…Because you’re blood-related, aren’t you ultimately just stuck as his sister? You’re just using him as an excuse to monopolize him in the end.”

Otowa remained expressionless as always, but her eyes gleamed.

Rika’s face turned bright red.

“Wh-what’s your problem, you all! I’m just protecting Kouta! I don’t push myself on him and tempt him like you do!”

“You keep saying you’re protecting him, but we all know you were sobbing and moping when Kouta was away on his middle school trip and the house was empty. Your dependency is so obvious.”

Aya grinned maliciously.

“Wh-what! How do you know about that…! I mean, that’s not true! I haven’t depended on him even a little bit!”

Rika’s voice cracked. The whole classroom murmured “Ooh…”

“See? Totally suspicious~!”

Yuri slapped the desk and burst out laughing.

“…Recording in progress. Permanently saving big sister’s disgrace.”

Otowa muttered.

“I told you to stop! And you three are the ones depending on Kouta—”

“Huh? I don’t want to hear that from you!”

The three and Rika fully clashed, sparks flying.

I clutched my head.

—This could explode at any moment.
